Finish the PEP

[iritkatriel]

This is a space to discuss anything else that we still need to do.

[iritkatriel]

1. Convert to .rst?
2. Write missing sections (or remove the headings): "Security Implications", "How to Teach This", "References"
3. Is "See Also" section staying in?
4. Decide on the title. How about "Exception Groups" ? or "except*"?
5. Add atexit use case

• Write missing sections (or remove the headings): "Security Implications", "How to Teach This", "References"

IMO the "How to Teach This" and "References" sections are particularly important for this kind of language change.

• Decide on the title. How about "Exception Groups" ?

"Exception Groups and except*"?

"Security Implications"

Are there any? There's no existing code that would suddenly become insecure with exception groups. As for the new code that would be written with the new syntax -- idk, usually we don't cover that in PEPs.

[iritkatriel]

Another use case, similar to the pytest finalizers situation: atexit currently raises the last exception any registered handler raises: https://docs.python.org/3/library/atexit.html#atexit.register

[gvanrossum]

It's beginning to look like this really has a lot of use cases!
